Problem context:
I have a C++ program and a web presence. Currently the way things are working I have made a control panel with javascript and html. And it send commands via an unimportant communication medium to control things or get information from the C++ program.
Now, when the C++ program launches, I'm making it run a
ShellExecute(NULL, "open", addressBuffer," --new-window", NULL, SW_NORMAL);
This is a way of launching the default browser with the given address. The addressBuffer in this case points to an intermediate HTML file that quickly turns around and uses the
window.open()
in Javascript to open the final popup, then closes itself.
The result is the user now has the popup control panel that I want them to have but the user's main browser window also gets given focus, un-minimized, and placed on a different tab than the one they had selected. (Basically pops up out of nowhere and selects a another tab)
Problem:
I'm looking for a way to launch a Chrome popup, without disturbing a previously open browser window. Any ideas or solutions would be very helpful.
Lastly, it's worth noting that the " --new-window" from the code above doesn't actually open a new window like you would expect. In this case it's actually doing nothing... If it did work, none of this would really be an issue.
I know this is wordy so thanks in advance for you time!

Alright, I came up with a solution.
Something about how ShellExecute processes it's commands was preventing the command line args to be passed in correctly.
My work-around includes grabbing the path to Chrome from the registry,
HKET_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\chrome.exe
Then simply doing a system() command with the chrome path "--new-window" and the web path.
Then I let the intermediate html page open it's popup and close itself.
Tada done.
Thanks.

I have been using Clojure, ClojureScript, lein, shadow-cljs, re-frame, reagent, Emacs, and CIDER to work on a Clojure/ClojureScript dynamic web app project.
Usually, I build the project by executing the command cider-jack-in-cljs in Emacs, choosing shadow-cljs, then shadow for REPL type, and, finally, app for the building option.
The application loads in localhost:3005 with a debugging dashboard. Apparently, this UI is called "re-frame-10x":
After clicking on the up-right arrow icon on the top-right:
I managed to pop out the debugging dashboard into a new window in Google Chrome. It was injecting some CSS and hiding a button on the webpage. Hence, I decided to "remove it" by popping-it out.
But, I would like to move it back to the browser tab that has localhost on the address. How to do it?
As suggested by #eugene-pakhomov, it was just closing that window. I must highlight that I had tried that before, the only problem was that there were multiple windows of that type. And all of them need to be closed for the process to work!
Not sure why the program opens multiple windows...
i'm struggling with the classic HTML input of type file. I was using it on my angular application and i had freeze sometimes, the whole browser became unresponsive, and the only thing that works is the scroll.
You can't click any buttons, select any text or even change tab on the browser for about 5 seconds. I tried a lot of different file type and sizes and it doesn't change any of this, it even freeze sometimes when i don't select any file in the explorer and i click the close button directly.
So I thought it was my implementation that was bad and i went to the Mozilla developper website where you have an example and I have exactly the same behaviour. I also tried to take only the HTML from the Mozilla website and put it alone on a .html file and again, same behaviour.
This does not occur 100% of the time, but I would argue that on my end it does it about 60/70 % of the times.
I tried it on chrome and Firefox (both up to date), on multiple computer (all running Windows though) and i have the same behaviour on all of them.
I don't have any error or anyting in the consoles.
I don't know what to do with this, i'm pretty sure it can't be the file's input on the whole web that are bugged, but i tried a lot of various things with always the same results. Should i report it somewhere? ( if so, where? ) Or what would you suggest to do to investigate this further?
I couldn't find anyone discussing this issue on the internet apart for this thread that had no solution, they also say in this thread that the bug is not reproducible in Edge, but i just tried and it does the same thing.
Thanks for reading me and for any help about this.
Chrome freezes for few seconds when after any use of file field.
It was because I had a shortcut in "Quick Access" menu in windows explorer. This shortcut has been linked with a folder shared by network. I've removed this shortcut and everything is good now.
Same here, I have a mapped network drive that is not responding, this make a 5 seconds delay. After unmapping the drive, no more delay. The delay is the same in firefox or chrome.
Same here, if you want to remove it, on Windows 10, click on the icon Quick access (blue star), then right click on the dead link appearing in the "Frequent folders" panel on the right panel and choose "Unpin/Remove from Quick access". There should be no error message.
In Google Chrome, I can type the following in a new browser:
pycharm://open?file=file_name
and press Enter. The result is that PyCharm IDE will launch and open the specified file. I have also come across similar links that launch other applications.
I tried to look for information about such links but did not reach any conclusions. Specifically, I would like to know:
what is the name of such a link?
who defines those links? Since I cannot find any documentation about those links on PyCharm's side, I am led to think that those links are some form of standard command that work for every external application?
how do those links work under the hood? Is it the browser spawning a new subprocess or does the browser somehow communicate the command to the OS which takes it from there?
I can also do the above programmatically:
window.open('pycharm://open?file=file_name', '_top');
How can I ensure that the focus switches to the target application? (Right now the application does indeed start, but the focus stays on Chrome.)
When a site gets stuck in chrome with the 'loading www.site.com' status, Is there anyway to know which of the elements on the DOM is delaying the load? for example, it can be an external js file or image that is taking long time to load. I tried using the network tab in the DeveloperTools, but it only shows the elements already loaded and the time they took. I couldn't find a way to see which element is stuck.
I found a way that I'm not sure it works in all cases, but it did for me. I used the Timeline tab (now shown in the Performance tab), it's one of the tabs in Chrome Dev Tools.
Open Chrome Developer tools (F12 or CMD + Alt + I in Mac) and click the Performance tab
Make sure you drag the grey timeline bar all the way to the right, you want to see the most recent section of events so you can find what's getting stuck:
Check just down below the records sidebar. If you don't see this like in the capture below, try toggling the icons, there are different view modes. Now, going all the way down I found these. It doesn't look like that's going well. Obviously some kind of infinite loop in some random code:
I couldn't find out if it was an extension itself or some other bit of code. Clicking through I only could find // Copyright 2014 The Chromium Authors. All rights reserved..
Checking in Incognito mode clear of extensions, the website loads just fine.
I'd also advise to check the Console tab to see if there are were any errors that might cause the infinite loading thing. You'll often find clues there.
Is it possible to access a Chrome Extension from outside the browser?
I would like to be able to run a command from my text editor (MacVim) that refreshes the page on which I am working. From reading the Chrome Extension documentation it looks like I could try something really hack-y, like opening a page that uses Chrome message passing to refresh another page, but there does not seem to be a strait-forward way to do this.
I am running Mac OS X. I've tried the shell command:
$ open <url>
But that opens a new tab every time in Chrome, so this doesn't help when I'm using the developer tools
You are right, there is no straight forward solution.
Your hacky approach is the simplest way to go. Only instead of messaging I would put a tab creation listener into background page, and when a tab with some special URL is created (http://example.com/?do=refresh) - close it and refresh the next selected tab. You will see new tab flickering, but that's as good as it gets.
You can also look into using WebSocket API, for which you would need to write a server side app (which you need to call from your editor somehow). Not sure how this all might turn out.
